Tension Rod
Identify parts for Metso jaw crushers, check models and drawing numbers, confirm materials and processes, and submit an inquiry.
Equipment, Models and Part Numbers
The tension rod connects the rear of the pitman to the spring assembly at the adjustment support. Spring preload keeps the toggle plate seated. Identify the required part against the Metso Nordberg C Series model and installed assembly.

Part identification
Metso equipment and part specifications
Tension rod identification
Provide the equipment nameplate, complete model, existing part number or drawing to identify the required part.
Materials and Processes
Review the following tension rod material and process information when assessing specifications and alternatives.
Carbon steel specification
Specify tension rod material, heat treatment, mechanical properties and thread production according to the model drawing. Inspect thread roots and the rod body for fatigue damage.
Alloy steel options
Assess alloy steel alternatives against rod loads, cross-section, threads and heat-treatment requirements, rather than equipment size alone.
Spring assembly
Specify the compression spring by wire diameter, coil diameter, active coils, free length, load-deflection relationship and material standard.
Wear and Replacement Criteria
Use the following tension rod wear patterns and replacement considerations during maintenance.
Main failure modes
Thread wear or damage, spring fatigue, rod bending and spring breakage.
Replacement Criteria
Stop and inspect if worn threads prevent locking or a spring is cracked, broken or permanently deformed beyond its design limit. Replace damaged parts.
Recommended Actions
Check spring preload regularly and confirm the nuts are locked after discharge-setting adjustment. Keep threads clean and lubricate as specified.
Information Needed for an Inquiry
Equipment model, such as C130; part number; whether a spring assembly is required; spring specifications; and quantity.
